Question

A ball moving on a table top eventually stops. Explain the reason.

Answer 1

Rolling ball stops after moving some distance due to friction force act opposite direction of motion of ball . you can see in figure .

Let any rolling ball of mass (m ) is moving with velocity v ,
normal reaction on ball (N) = mg
due to motion , friction force appears on contact surface and start to opposing motion of rolling ball .
hence,
fr = uN = umg act on contacting surface, so, after some time due to friction force rolling ball comes rest .
